What We Loved: Unfortunately, this photo from my iPhone doesn't show the awesome details that make Mark's outfit hot on a particularly chilly spring day in New York. It's all about texture. The subtle herringbone pattern on his charcoal gray Chinook pea coat, the contrast stitching on his G-Star shirt and silky woven pattern of his Sisley tie add polish and a little drama to an otherwise classic look.

We love Mark's mix of prep-school style and rock and roll edge—notice the rolled down Kenneth Cole boots and the tattoos that peek over his buttoned up shirt collar and tie.
